Thr problem with Thorium is that it is classified as source material the same as Uranium. Natural Uranium is fissile in a heavy water moderated reactor, Thorium is only slightly radioactive, and should be regulated like all other radioactive products, like household smoke detectors and medical isotopes.
Congress should immediately declassify Thorium as a source material. This would again enable U.S. to mine rare earth materials like China and the rest of the world.
The video speaks for itself and is well worth watching. Especially listen at 15:30 min why molten salt reactors were abandoned.
